Alien conspiracy site UFO Sightings Daily says that an skeleton remains of a creature on Mars can be seen on this photo taken by the Mars rover Curiosity. The photo zoomed in on the "skeletal remains"

The online community of UFO true believers is bustling with excitement.

Twice in the past week, dedicated UFO watchers have reported spotting an Unidentified Flying Object near the International Space Station, via NASA's live webcam.

The first such sighting was Aug. 4, when blogger Scott Waring of UFO Sightings Daily saw a "glowing disk" on the live feed.

"Hey everyone, I was watching the live cam and caught this glowing disk in the distance," Waring wrote in his blog post. "I took a screenshot of the UFO and enlarged it. It has a long line down its middle and a dome on its top, but is rectangle (sic) on its lower bottom."

Waring must have a good eye. Looking at the enlarged screenshot, it's hard to see much besides a blurry blob.

On Aug. 7, however, he posted another person's find from NASA's HD cam, which Waring described as an "amazing catch by a famous UFO researcher."

The Aug. 7 sighting is posted on YouTube under the name Streetcap1.

"It shows incredible detail of what this UFO looks like," Waring wrote in describing Streetcap1's video. "Mostly its a glowing five pointed UFO."

a YouTube user known as Streetcap1 saw what he or she described as a "glowing five-pointed UFO."
